“The Stoics believed that the Universe itself was a divine being, a living thing endowed with soul and reason. All conventional gods were merely names for different powers of the cosmic God. Everything in the earth and heavens was the actual substance of God. The Stoics were physicalists, and yet they saw this God as a being with intelligence and purpose, a "designing fire" pervading every part of the universe. "God is the common nature of things, also the force of fate and the necessity of future events," wrote Zeno's follower Chrysippus. "In addition he is fire, and the ether . . Also things in a natural state of flux and mobility, like water, earth, air, sun, moon and stars; and he is the all-embracing whole.”
